Optimum Planting Density of Mung Bean for Lordegan Region

 Mung bean is one of the important beans in human nutrition. The aim of this study was to determine the most appropriate planting density for the highest yield of mung bean (Vigna radiata L.) cultivars in Lordegan region. The study was carried out as a factorial experiment in a randomized complete block design with three replications. Factors included four mung bean cultivars namely Parto, VC6173A, VC637194 and Lordegan Local mung bean plus three different planting densities of 30, 40 and 50 plants per square meter. Flowering date, physiological maturity date, plant height, number of pods per plant, number of seeds per pod, 100-seed weight and seed yield were measured. Results of combined analysis of variance over two years showed that genotypes were significantly different in studied traits (except for number of seeds per pod). The effect of planting density was significant on all traits (except for 100-seed weight and the number of days to maturity). The interaction between genotype and density was not significant for any of the traits. The highest grain yield (1357.8 kg/ha) was obtained from VC6173A line a density of 40 plants per square meter.
